SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
432 PM AKST SUN FEB 8 2015

.ANALYSIS AND UPPER LEVELS...
THERE IS AN ELONGATED UPPER LOW STRETCHING FROM THE EASTERN
ALEUTIANS ACROSS KODIAK ISLAND TO THE GULF COAST...CENTERED JUST
TO THE SOUTHWEST OF KODIAK ISLAND. A FRONT WITH SEVERAL EMBEDDED
SURFACE LOWS STRETCHES FROM THE CENTER OF THIS LOW TOWARD THE
NORTHEAST...ESSENTIALLY RIGHT ALONG THE GULF COAST. THE ATMOSPHERE
WITH THIS FRONT IS FAIRLY UNSTABLE WITH NUMEROUS SHOWERS VISIBLE
ACROSS THE GULF. NORTHERLY FLOW PERSISTS ACROSS THE BERING SEA AND
ALEUTIANS WITH ITS ASSOCIATED CONSIDERABLE CLOUDINESS AND SHOWERS.

&&

.MODEL DISCUSSION...
THE NUMERICAL MODELS ARE IN MUCH BETTER AGREEMENT THROUGH THE
SHORT TERM THAN THEY HAVE BEEN THE LAST FEW DAYS. THUS THE
FORECAST CONFIDENCE IS A LITTLE HIGHER THAN NORMAL FOR THE
AFTERNOON PACKAGE. THE HI-RES MODELS WERE PREFERRED DUE TO THEIR
BETTER DEPICTION OF SMALL SCALE FEATURES THAT ARE IMPORTANT TO
THE FORECAST.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (DAYS 1 THROUGH 3)...
A WEAKENING BUT UNSTABLE LOW MOVING INTO PRINCE WILLIAM SOUND
WILL CONTINUE TO BRING ACCUMULATING SNOW TO THE WESTERN KENAI THIS
EVENING...ESPECIALLY ALONG THE COAST WHERE GUSTY OUTFLOW WINDS
WILL ALSO CREATE AREAS OF BLOWING SNOW NEAR SEWARD AND WHITTIER.
THERE IS AN OUTSIDE CHANCE THAT A FEW OF THESE SHOWERS MAY TRAVEL
OVER THE CHUGACH MOUNTAINS INTO THE ANCHORAGE BOWL THIS
EVENING...HOWEVER WITH THE DRY LOW LEVELS FROM CONTINUED
NORTHEASTERLY FLOW THESE WILL LIKELY STRUGGLE TO REACH THE GROUND
(OR BY VERY LIGHT AND SHORT LIVED IF THEY DO). THIS SAME LOW IS
EXPECTED TO BRING ONE OF THE HEAVIEST SNOWFALLS OF THE SEASON TO
CORDOVA...ESPECIALLY IF NUMEROUS SHOWERS CONTINUE TO REFORM AND MOVE
OVER THE AREA AS THEY DID EARLIER THIS AFTERNOON. SNOW SHOWERS
WILL THEN REMAIN OVER THE GULF COAST WHILE SLOWLY WEAKENING INTO
TUESDAY BEFORE DIMINISHING IN ADVANCE OF A FRONT MOVING INTO THE
SOUTHERN GULF TUESDAY MORNING. THIS FRONT WILL THEN SPREAD INTO
THE NORTH GULF LATE TUESDAY...BRINGING A PATTERN CHANGE TO MUCH OF
THE SOUTHERN MAINLAND FOR THE MIDDLE OF NEXT WEEK.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA...
AN UPPER LEVEL RIDGE IS POSITIONED THROUGH THE BROOKS RANGE
RESULTING IN CONTINUED NORTHERLY WIND OVER SOUTHWEST ALASKA.
THIS WILL RESULT IN CLEAR AND DRY CONDITIONS FOR MAJORITY OF THE
REGION. THE WINDS ARE BEGINNING TO DIMINISH AND THE TEMPERATURES
WILL GRADUALLY BEGIN TO WARM...WHICH WILL KEEP THE REGION ABOVE
WIND CHILL ADVISORY LEVELS. THE EASTERN ALEUTIANS HAVE AN
INVERTED TROUGH EXTENDING INTO THE ALEUTIAN RANGE. THIS WILL
PRODUCE SCATTERED SNOW SHOWERS SOUTH OF KING SALMON THIS EVENING.
BY MONDAY A WEATHER FRONT WILL BE APPROACHING THE EASTERN
ALEUTIANS FROM THE PACIFIC SIDE. THIS WILL BRING WARMER
TEMPERATURES TO THE SOUTHWEST ALASKA REGION FOR THE NEXT SEVERAL
DAYS AND GALE FORCE WINDS ALONG THE WESTERN CAPES AND ALASKA
PENINSULA BY TUESDAY.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS...THERE WILL CONTINUE
TO BE WEAK SNOW SHOWERS ALONG THE EASTERN ALEUTIANS AND THE
CENTRAL TO EASTERN BERING SEA AREA. THERE WILL BE AREAS OF
BLOWING SNOW WITH REDUCED VISIBILITIES AT TIMES ALONG THE ALEUTIAN
CHAIN AND THE PRIBILOF ISLAND THROUGH MONDAY. THIS IS ASSOCIATED
WITH THE UPPER LEVEL ELONGATED CLOSED LOW OVER THE EASTERN
ALEUTIANS WITH A TROUGH EXTENDING TOWARDS DUTCH HARBOR. THE
CENTRAL BERING SEA HAS AN UPPER LEVEL NORTHEAST TO SOUTHWEST JET
STREAK OF 70 KNOTS WITH GALE FORCE WINDS REFLECTED AT THE SURFACE.
THESE NORTHEASTERLY WINDS WILL CONTINUE THROUGH MIDWEEK. A NORTH
PACIFIC LOW WILL TRACK TOWARD THE EASTERN ALEUTIANS WITH AN
ASSOCIATED WEATHER FRONT EXTENDING INTO THE SHUMAGIN ISLANDS
REGION BY MONDAY. THIS WILL BRING WARMER TEMPERATURES WITH UPPER
END GALE FORCE WINDS ALONG THE CENTRAL TO EASTERN ALEUTIANS. THERE
WILL BE ABUNDANT PRECIPITATION WITH THIS SYSTEM AND WILL SPILL
OVER INTO THE BERING SIDE THROUGH TUESDAY.

&&

.LONG TERM FORECAST (DAYS 3 THROUGH 7)...THE INITIAL FRONTAL
SYSTEM ASSOCIATED WITH THE LARGE UPPER LEVEL LOW WHICH WILL BE
SETTING UP STATION FOR QUITE A WHILE SOUTH OF THE ALASKA
PENINSULA WILL APPROACH THE NORTHERN GULF COAST TUESDAY NIGHT AND
ROTATE INLAND AS IT FALLS APART ON WEDNESDAY. NORTH TO
NORTHEASTERLY GAP WINDS WILL INCREASE OUT AHEAD OF THIS FRONT IN
LOCATIONS SUCH AS SEWARD...PRINCE WILLIAM SOUND...THOMPSON PASS
AND THE COPPER RIVER DELTA AS THE OFFSHORE GRADIENT TIGHTENS
FAIRLY RAPIDLY TUESDAY NIGHT. WITH A CONTINUING SUPPLY OF LOW
LEVEL COLD INLAND AIR AND OVERRUNNING MOISTURE...WILL NEED TO
KEEP AN EYE ON THESE LOCATIONS FROM A SNOW AND/OR MIXED
PRECIPITATION PERSPECTIVE THROUGH THE DAY WEDNESDAY. ALONG THE
WEST SIDE OF THE CHUGACH MOUNTAINS DOWNSLOPING EAST TO SOUTHEAST
FLOW WILL WRING OUT MUCH OF THE AVAILABLE MOISTURE KEEPING
PRECIPITATION AMOUNTS LIGHTER...AT LEAST FOR THIS INITIAL FRONT.

NUMEROUS ADDITIONAL TROUGHS AND FRONTAL SYSTEMS WILL ROTATE UP AND
OVER THE AREA THROUGH THE REMAINDER OF THE WEEK AND INTO NEXT
WEEKEND WITH EACH ONE WARMING AND MOISTENING THE AIR MASS A BIT
MORE. RECENT MODEL RUNS (COMPARED WITH THOSE OVER THE LAST
SEVERAL DAYS) HAVE BACKED OFF A BIT ABOUT THE AMOUNT OF WARM AIR
BEING PUMPED UP INTO THE AREA BY SOUTHERLY FLOW AND ARE NOW ALSO
DIRECTING THE WETTER SYSTEMS A LITTLE FURTHER TO THE EAST.
NEVERTHELESS...THE TREND OF STEADILY INCREASING TEMPERATURES WITH
PERIODIC ROUNDS OF PRECIPITATION STILL LOOKS QUITE SOUND.
